Method using implantable wireless transponder using position coordinates for assessing functionality of a heart valve

Abstract

A method for assessing functionality of a valve in a heart includes providing a position sensor that is a wireless transponder for transmitting or receiving an ultrasound wave for determination of position coordinates of the position sensor at the point; implanting the wireless transponder at a point on the valve; and using a position determining system for determining whether the valve is functioning properly based on position coordinates of the wireless transponder.

1. A method for assessing functionality of a valve in a heart, the method comprising the steps of:
 providing a wireless transponder for transmitting or receiving an ultrasound wave for determination of position coordinates of the wireless transponder; 
 implanting the wireless transponder at a point on the valve; 
 monitoring movements of the valve and the wireless transponder attached at the point on the valve using a position determining system operated by using ultrasound waves for determining position coordinates of the wireless transponder by transmitting the ultrasound wave to the wireless transponder or receiving the ultrasound wave from the wireless transponder; 
 determining position coordinates of the wireless transponder using the position determining system; and 
 determining whether the valve is functioning properly based on the position coordinates of the wireless transponder.
